Anti
Aliasing & Texture Compression
You've probably red it on our site already in one of our articles. NVIDIA developers
leaked Detonator drivers version 5.xx We found some new enhancements in these
drivers. The new drivers support Full Scene Anti Aliasing (FSAA). FSAA removes
the so called 'jaggies' from your game. If you draw a straight line (under an
angle) using a paint program and you zoom in, you will discover that the line
looks like a stairway. To remove this and make the line look like a line
points in different colors are added to the side of the line to make it look
more like a real line.

You eyes are
actually being fooled by letting you think that it is a straight line without
the stairway effect. FSAA comes at a price ... and this factor is performance.
In higher resolutions the performance can drop with at least 50% of your
framerate easily. At this time you should not expect miracles from FSAA. It
works in all OpenGL games like Quake III, Soldier of Fortune, Half-Life etc. and
hey, it surely does look cool. Recently there where some NVIDIA drivers that
have leaked. The leaked drivers are now up-to version 5.30. They offer
good performance and even Full-Scene Anti-Aliasing in Direct3D.
However, the performance hit is huge.
We can demonstrate FSAA
perfectly, please look at the image below. You'll notice a distinct difference
between the two images. You can use your mouse pointer to move the
lens and see what FSAA does in close-up.
Another newbie
in the v5.xx detonator driver (officialy called Detonator2) release was support for Texture Compression. After
shaking hands and burying a cold war with S3 we instantly saw this cool method
integrated in the new drivers. The large advantage from S3TC (S3 Texture
Compression) is that more textures will fit into the videocards memory making
textures bigger, higher quality which results in a clearer and sharper image.
